Intercept Module Delays Wake Packets to Reduce Signaling Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The periodic waking of mobile user devices to access public data networks increases signaling load on mobile networks, negatively impacting the ability to support user-initiated connections.
Innovation Solution
An intercept module is introduced that delays packets related to mobile user device wakeups, thereby extending the duration of wake events and reducing the frequency of subsequent wakeups, thus decreasing the signaling load on the mobile network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If mobile user devices periodically wake up to access the public data network, then battery life is conserved, but signaling load on the mobile network increases
Solution Approach 1:
The network side proactively delays packets before the mobile device wakes up, preventing the device from needing to wake up at all. This preliminary action on the network side eliminates the wakeup signaling entirely, resolving the contradiction by reducing signaling load while maintaining battery savings.
Solution Approach 2:
A packet delay function acts as an intermediary between the mobile device and the network, buffering packets and releasing them at optimized times. This intermediary prevents unnecessary wakeups by ensuring data is ready when the device naturally wakes, reducing signaling load without impacting device battery life.
2Loss of information
If mobile user devices periodically wake up to check for new data, then data freshness is maintained, but the ability of the mobile network to support user-initiated connections deteriorates
Solution Approach 1:
The network pre-delivers or buffers data before the device wakes up, so that when the device does wake, data is already available or can be delivered immediately. This eliminates the need for repeated wakeups to check for new data, maintaining data freshness while freeing network resources for user-initiated connections.
Solution Approach 2:
The packet delay function maintains continuous data availability in the buffer, ensuring that data delivery is ready whenever the device wakes. This continuous preparation eliminates gaps in data delivery and reduces the frequency of wakeups needed to maintain data freshness, thereby improving network productivity.

AI summary
One or more packets associated with a wakeup event for a mobile user device is/are delayed, thereby extending the duration of the wakeup event. Because the duration of the wakeup event is extended, the start of the next wakeup event for the mobile user device is delayed by a time interval, and therefore the signaling load on the mobile network is reduced during this time interval compared to the signaling load that would have been on the mobile network if the start of the next wakeup event had not been delayed. If the delayed packet(s) is/are data packet(s), then the disclosure presents a solution which involves data to solve a problem relating to signaling.
